+%% this is a simple example to read and play a wave file with matlab
+
+% set a string variable to a wave filename we want to open:
+toneFileName = "wav/single_tone_piano1.wav";
+% read the content of the wave file:
+[data,fe] = audioread(toneFileName);
+% data is a matrix with 2 columns if the sound is stereo; keep the mono to ease further processing
+data = data(:,1); 
+% get the number of sample in vector data
+N = length(data);
+% play the sound in the audio output:
+soundsc(data,fe);
\ No newline at end of file
